quickly and easily applied, rugged and secure, and of neat appearance.

v 15 A further object of my invention is to provide such a device which may be applied to a standard without the necessity of any extraneous securing means, the device itself being adapted to frictionally engage the standard and thus securely retain itself in position as long as desired.

A particular object is to provide such a device which is especially adapted to be used in conjunction with anchor shells as described 12: and claimed, for example, in mycop'ending application S. N. 33,776 filed May29, 1925, and in other applications.

Many other ob1ects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims. In the drawing, wherein like reference characters indicate like or corresponding parts: H V

Fig. 1 represents an elevational View of a device embodying my invention shown mounted on a fragmentary portion of a lighting standard, a portion of the ceiling 4,1 being fragmentarily shown;

Fig. 2 is a sectional view taken on line 2-2 of Fig.1;

Fig- 3 is a sectional view taken on line 33 of Fig. 1; and i Fig. 4 is a longitudinal sectional view of the device shown in the other figures before it is mountedupon a standard.

The numeral 10 indicates a portion of a ceiling or similar supporting wall from which there depends a standard 11. The standard 11, of course, may represent'any type of standard adapted to support an obect. As shown clearly in Fig. 2, the stand- I ard 11 is threaded as at 12 into a hollow anchor shell'13. This anchor shell may be of the type shown in my copending application, Serial Number 38,7 7 6, filed May 29, 1925, or of any other suitable type. I

A ceiling plate embodyingmy invention is preferably formed of atubular body portion 15 and a frusto-conical portion 16. In the embodiment disclosed, the entire ceiling plate is formed of an integral coiledmember preferably of resilient metal wire or other suitable material. It will be noted from an inspection ofFig. 4-. that the tubular body portion 15 is not truly cylindrical in shape but deviates from a straight line. The reason for this construction is as follows: When it is desired to apply a plate embodying my invention, the plate is slipped upon the stand ard, the frusto-conical portion being disposed toward the ceiling or'wall, and the plate is then moved to its extreme position adjacent the ceiling or wall as shown in Figs. 1 and 2. When the device is placed upon the standard, the resilient tubular portion 15- becomes straightened to a truly cylindrical shape'asshown in Figs. 1 and 2. However, because of its resilience and tendency to deviate from "a straight line as originally formed, this tubular portion securely grips the standard 11 and, thus prevents displacement of the plate. Hence, the plate is re-; tained securely on the standard solelyv by 00 lit] frictional contact and the use of extraneous securing means, such as screws, cement, etc, is entirely obviated. he internal diameter oi the tubular portion 15 is preferably substantially equal to the external diameter of the standard 11. However, the diameter of .e portion 15 may accommodate satisfactorily various sizes of standards due to its frictional contact resulting from its tendency toward deformation.

Obvious y, my invention may take various other forms besides that ol the embodiment illustrated and c cribed above; for example, the body portion 15 may be formed of any resilient material and deformed so that its tendency toward deformation and resilience will tend to retain it frictionally on a standard; furthermore the portion 16 need not be trusto-conical, but may be oi any desired contour of pleasing configuration which will relieve the abruptness of the juncture point between ceiling and standard. An advantage of my device is that it may easily be displaced, when desired, from its position at the point of uncturo between the standard and the wall or ceiling as shown dotted in Fig. l, in order that the ceiling may readily be cleaned or painted at this point and the plate itself cleaned or painted. It may then be moved back into place. Hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent 1.. In a ceiling plate of the kind described, a tubular body portion formed of resilient material, the axis of said body portion deviating from a straight line, and a main portion joined to said body portion and adapted to Contact with a ceiling, or the like.

2. In a ceiling plate of the kind described, a tubular body portion formed of resilient material, the axis of said body portion deviating from a straight line, and a frustoconical portion joined to said body portion and adapted to contact with a ceiling, or the like.

3. In a ceiling plate of the kind described, a tubular body portion comprising a helical coil of resil nt material, said body portion having its axi deviating from a straight line to adapt said body portion to frietionally grip a rod or the like, and a portion joined thereto and adapted to contact with a ceiling, or the like.

4;. In a ceiling plate of the kind described, a tubular body portion comprising a helical coil of resilient material, said body portion having its axis deviating from a straight line to adapt said body portion to frictionally grip a rod or the like, and a trusto-conical portion joined to sai d first-named portion and adapted to contact with a ceiling, or the like.
